It is needed to check if the proposed pixels format is valid before
updating context bit depth and other internal states.
Stop using ctx->bit_depth to check format depth match and return
result to the caller.

version 4:
- Change hantro_check_depth_match() prototype to avoid using
ctx->bit_depth
- Return the result of hantro_reset_raw_fmt() to the caller.
